Compare

General overview

Tool for visualizing and statistics of two columns over concurrent time period. This feature provides a set of plots and tools divided across these tabs:

Scatterplot. Graphs of scatter plots, histogram and cumulative distribution graph.
Monthly Scatterplot. Monthly scatterplot
Time Series. Graphs of reference data, estimate data and differences between them
Heatmap. Heatmap plot of reference data, estimate data and difference between them
Analytical plot. Specific analytical graphs

Compare window has few default options when opened that can be changed. Double-clicking on graphs in the Scatterplot or Analytical plots tab will maximize the graph.

Component	Description
Reference dataset	Reference dataset.
Reference column	Reference column
Estimate dataset	Estimate dataset
Estimate column	Estimate column
Text box	Basic text statistics for the current selection.
Aggregation	Output time step.
Min of valid points	Minimum required number of original records (in %) for summarizing the output interval. If this condition is not met (e.g., there are less than 30 1-minute records in hourly output interval, while we require 50% minimum), the output interval is empty - filled by NaN value.
Year/Month	Filter data by year, month or year and month
Date	Filter data by date and/or time
Period of day	Filter data by period of the day, similar to filter data by solar elevation
Sun elevation	Filter data by sun elevation
Start at	If checked, histogram starts at this value
Histogram - Bin size	Set width of bins
Histogram- Number of bins	Set number of bins of histogram
CDF- Number of bins	Set number of bins of CDF
Lock heatmap	If checked, heatmap difference plot will not change the color scale range.
Show monthly stats	If checked, statistics are shown in monthly graphs.
Flags	If checked, data are filtered by flag values from flag column
Valid	Check valid flags
Select All	Check all flags
Deselect All	Deselect all flags
Flag values	Dataset flags from dataset flag scheme
Redraw	Redraw all graphs.
